2x+1>0 x-4<0
Kia tōraro te otinga, me tauaro rawa ngā tohu o te 2x+1 me te x-4. Whakaarohia te tauira ina he tōrunga te 2x+1 he tōraro te x-4.
x\in \left(-\frac{1}{2},4\right)
Te otinga e whakaea i ngā koreōrite e rua ko x\in \left(-\frac{1}{2},4\right).
x-4>0 2x+1<0
Whakaarohia te tauira ina he tōrunga te x-4 he tōraro te 2x+1.
x\in \emptyset
He teka tēnei mō tētahi x ahakoa.
x\in \left(-\frac{1}{2},4\right)
Ko te otinga whakamutunga ko te whakakotahi i ngā otinga kua whiwhi.
